Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

I'm trying to make my led strip be remote controlled and I encountered a problem!
This Scott Marley's esp32 spectrum analyzer got me going into esp32.

Need Help Figuring Out The Problem in Switching from Arduino to ESP8266 for My LED Display.
It is still bugged, however I've managed to pin it down to one single issue I believe. (thanks to major help.) The sampling rate from the analog input is extremely slow for some reason. It takes a whole 2 seconds to take 8k samples from the A0 pin for a FFT. The code that this is being copied off of online found here: https://github.com/s-marley/ESP32_FFT_VU/blob/master/ESP32_FFT_VU/ESP32_FFT_VU.ino runs 40k samples at 9.2uS even though the code I have for that section is a carbon copy.

ESP32 Audio Spectrum Display, forked from S-Marley
Build this based on project from S-Marley on Github (https://github.com/s-marley/ESP32_FFT_VU). My fork is at https://github.com/christiansuryanto/ESP32_FFT_VU . Preview video on Youtube https://www.youtube.com/shorts/Jht9vsqAN1U

audio reactive patterns
Scott Marley has done a great demo with sound reactive lights. The code is very close to what you want with multiple patterns accessed via a button. The code ishere

Here's some of my sound reactive FastLED videos.
I'm currently making some mini VU meters on 8x8 and 16x16 matrixes (matrices?). I'd love to be abe to use my patterns from here https://www.youtube.com/watch?v=Mgh2WblO5_c. Code on GitHub here: https://github.com/s-marley/ESP32_FFT_VU/blob/master/ESP32_FFT_VU/ESP32_FFT_VU.ino

Code format question
In the previously linked version comparing colorCurrent.h == colorTarget.h or colorCurrent == colorTarget without the .h worked the same since the colors were fully saturated and at full brightness. Comparing colorCurrent == colorTarget compares the H,S, and V numbers all at the same time.

what the work of EVERY_N_MILLISECONDS_I ?
Use the first one for regular unchanging intervals. Use the second one when you need the interval to change over time. Here's one of Marmilicious' examples.
- Blinking stars
- stretching and then compressing a rainbow on a strip

Controlling WLED-ESP with another Arduino
Depending on the complexity of the animations you want, you could power them through the Arduino directly with a library like FastLED. https://github.com/marmilicious/FastLED_examples/blob/master/MIDI_test_v1.ino is an example.
- changing brightness of the individual led's?
- hopefully, last time asking for help...
- help again
- Addressing multiple individual Leds at once

More Coding Help Needed!
Take note in my example: https://github.com/marmilicious/FastLED_examples/blob/master/custom_pixel_array.ino
What are some alternatives?
When comparing ESP32_FFT_VU and FastLED_examples you can also consider the following projects:
WLED - Control WS2812B and many more types of digital RGB LEDs with an ESP32 over WiFi.
FastLED - The FastLED library for colored LED animation on Arduino. Please direct questions/requests for help to the FastLED Reddit community: http://fastled.io/r We'd like to use github "issues" just for tracking library bugs / enhancements.
Striptease - Sexy, audio-responsive effects on LED strips.
